MANUFACTURING METHOD OF CARBON FIBER

摘要

PURPOSE: A method for fabricating a carbon fiber is provided to remarkably improve opening fineness. CONSTITUTION: A method for fabricating a carbon fiber comprises: a step of preparing a polyacrylonitrile-based precursor spinning solution; a step of spinning by dry/wet spinning method from a spinneret; a step of solidifying in a solution containing ZnCl_2; and a step of drawing solidified carbon precursor fiber inside.
